Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.

Root seedling is the root of plant production. With a good root plant, it will grow healthily. Therefore, it is best to use plant regulators at seedling stage, such as Jinbao root seedling, which is a protective agent for vegetable seedlings and can be mixed in nutritious soil when used. Or in the colonization, transplanting, the bed in the late growth stage, rooting, foliar spray application, Jinbao root seedlings can increase the temperature, germination early, and promote weak seedlings into strong seedlings. When planting and transplanting, the seedlings are quickened and rooted, and they enter the high-yield period in advance. They can prevent leggy, prolong the harvest period, and resist disease and stress. For details, please visit the website or consult.
